Review on 📱 Vive Precision EKG ECG Monitor with App - Portable Heart Rate Pocket Device - Detects Irregular Cardiac Rhythm - Wireless Electrocardiogram Test - Smartphone Compatible by Trisha Hunter

I got this for reassurance because I've had a mild heart attack and it will be difficult to even come and get wrong readings sync it to mine smartphone after installing the app. This will cause you more stress than it will bring you peace of mind. I have a Samsung GalaxyJ7 skypro, I can connect the device to the phone but not to the app itself. When I was using it someone was monitoring the nap and breathing and didn't make it clear what the machine was saying. Also missing was the suitcase he said came with him.
